HP7640 false paper jam

[ANDYTROUT]

I keep getting the 'paper jam' alarm despite no actual jam.  I've tried all of the recommended fixes (cleaning rollers, unpluging, etc).  Any other ideas?

Hi @ANDYTROUT,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

Dealing with a persistent false paper jam alarm can be frustrating. Here are additional steps you can try to resolve the issue with your HP Envy 7640 printer:

Reset the Printer:

• Turn off the printer.
• Unplug the power cord from the back of the printer.
• Wait for about 1-2 minutes.
• Plug the power cord back in.
• Turn on the printer.

Update Firmware/Driver:

• Ensure that your printer's firmware and drivers are up to date. Visit the HP website to check for the latest updates specific to your printer model.

Check for Obstructions:

• Inspect the paper path carefully for any obstructions. Even small pieces of torn paper or debris can trigger false paper jam alerts.

Paper Sensor Check:

• Check for any paper sensors along the paper path. Make sure they are not stuck or damaged.

Adjust Paper Guides:

• Ensure that the paper guides in the input tray are adjusted properly to fit the size of the paper you are using.

Use High-Quality Paper:

• Ensure you are using high-quality, undamaged paper. Poor-quality or damaged paper can sometimes trigger false paper jam alerts.

Paper Type and Size Settings:

• Make sure that the paper type and size settings in the printer driver match the paper loaded in the input tray.

Perform a Hard Reset:

• Turn off the printer.
• Disconnect all cables and USB connections.
• Wait for about 5 minutes.
• Reconnect all cables and turn the printer back on.

Check for Mechanical Issues:

• Carefully inspect the printer for any mechanical issues, such as broken parts or foreign objects that might be causing the false alarm.

I hope this helps. 

Take care and have a good day.-
